Wirewound Potentiometers - Interfacing with 110V

Other Hardware General Electronics

Hi All, I thought I posted here this morning, but maybe I violated a rule or the post did not make it through?

I was looking for a WX14-12 wirewound single turn potentiometer in 560 ohm. I find the exact part in different values at aliexpress, but cannot find the value I need so that is what I'm searching for. It is for the speed control of a milling machine power feed, and I think the circuit is 110V.

The thought then came to me that I could rather interface Arduino to the 3 wires and direction switch instead. I was also wondering what components and circuit could be safely used instead. This is appealing because I could have better and more versatile control.

Thanks

Assuming you wanted to buy the potentiometer would this part fit the bill?

As far as using the Arduino you could use a digital potentiometer like this: http://www.mouser.com/ProductDetail/Maxim-Integrated/MAX5460EXK+T/?qs=sGAEpiMZZMuD%2F7PTYBwKqfvOGymLeqhpGALl59PJPns%3D

It is simply controlled by a serial 2 wire interface to control it, if that specific IC doesnt meet your minimum power or voltage requirenments I'm sure there are digital pots that can handle higher values that can be purchased online.
